TOOL.

Application filed April 13, 1926. Serial No. 101,737.

The present invention relates generally to tools. and more particularlyto wrenches; and has for its principal object to provide a structureembodying the features of an ordinary monkey wrench and Stillson wrench,and also the features of a solid wrench.

A still further very important object of the invention is the provisionof a wrench of this nature, which is capable of being easily and quicklyadjusted.

Another very important object of the invention resides in the provisionof a device of this nature which is exceedinglysimple in itsconstruction, easy to 'manipulate, strong, durable, inexpensive tomanufacture, and otherwise well adapted to the purpose for which it isdesigned.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel featuresofconstruction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing Fig. 1 is a side elevation of the wrench embodying thefeatures of my invention,

Fig. 2 is a detail section taken substan tially on the line 2-2 of Fig.1,

Fig. 8 is a. perspective view of one of the removable parts of thewrench. and

. Fig. 4 is a transverse section taken substantially on the line 1 1 ofFig. 1.

Referring to the drawing in detail, it will be seen that 5 denotes anelongated shank being provided at its edge with. rack teeth 6. At oneend of the shank 5 there is provided a fixed jaw 7. A movable jaw 8 isformed on a shank or block 9 having rack teeth 10 for meshing with teeth6. A yoke 11 of a substantial U-shaped formation including sidesconnected by a bight extends about the shank 5 and is engaged with thelower end of the block 9 by ascrew 12. A

set-screw 13 is threaded through the yoke 11 for engaging the other edgeof the shank 5, so that by screwing in on the set screw 13, the teeth 10may be maintained in mesh with the teeth 6, thereby holding the movablejaw in a set position in relation to the fixed jaw. V

The lower inside corner 14 of the block 9 is rounded so that the blockmay swing to some extent on the screw 12 and the jaws 7 and 8 willoperate as the ordinary jaws of a Stillson wrench. On the lower end ofthe shank 5, there is formed a loop frame 15 and longitudinallyextending ribs or rack teeth 17. A set screw 18 is threaded through aportion of the loop 15. A plate 19 is receivable in the loop 15 and isprovided withlongitudinally extending ribs 20 for meshing with the ribs17. Thus by loosening up on the set screw 18, the plate 19 may beadjusted to different positions in relation to the shank and the setscrew then tightened to maintain said plate in said adjusted position.

A jaw 21 is provided on the end of the shank for coop-crating with a jaw22 on the plate 19. These jaws 20 and 22 provide an end wrench. Theterminal of the jaw 21 is beveled to form a screw driver blade as isindicated at 23.

From the above description, it will be seen that I have provided a verydesirable, compact, and convenient construction which will be capable ofbeing manufactured at a low cost, being strong and durable. The variousmovable parts are capable of ready and easy adjustment so that thewrench may be used under a large number of different and commoncircumstances.

The present embodiment of the invention has been disclosed in detailmerely by way of example, since in actual practice, it attains thefeatures of advantage enumerated as desirable in thestatement of theinvention and the above description. It is apparent that changes in thedetails of construction, in the combination and arrangement of parts,may be resorted to without departing from the spirit or scope of theinvention as hereinafter claimed. or sacrificing any of its advantages.

I claim as new is A wrench of the class described including a jaw havinga shank extending therefrom and provided with rack teeth on one edge, asecond jaw having a shank, said shank of the second jaw being providedwith rack teeth throughout the length of one edge meshable with thefirst-mentioned rack Having thus described my invention, what adjustedpositions in relation to the fixed jaw, the inside corner of the secondshank being rounded for the purpose of pern'iitting the swinging of theseconc shank towards said pivot means.

In testimony whereof I affix my signature.

JEROME J. B. DREESEN.
